Working on this this week actually, after more use, I agree that it should be available.
In regard to this, I tried to follow another chat services design implementation.
The thing I now realize is that the sidebar background is a darker/different color. So turning the green “online” circle to white when active make sense. I think for the fully theme the issue is that it is turning the same color as the sidebar background, and causing confusion.
I don’t see the default light scheme on any new instance, so this is not related to the theme.
To have the Light scheme on the colors section I’d need to add a new color scheme and then it’s suggested I base it on the default light scheme. But the Light scheme is not present on the colors section by default.
If anyone’s running into an issue with there not being a Light color scheme, the method you’re describing should work to create one. Click the “New” button, then create a new color scheme based off the “default light” scheme.
